Efficiently Setting up and Deploying Your API Gateway: A Comprehensive Guide

Setting up and Deploying an API Gateway

Are you looking to set up and deploy an API Gateway? If so, you’re in the right place! In this article, we will discuss the steps needed to create and deploy an API Gateway efficiently.

The set-up and deployment process consists of two main sections: setting up the API Gateway and deploying the API.

Setting up the API Gateway

You will need to create an API using the Amazon API Gateway service. Once you create the API, you can configure it to handle incoming HTTP requests.

Here are some steps to follow:

Creating the API

To create an API Gateway, you will need to log in to the AWS Management Console. From there, navigate to the Amazon API Gateway service, and click on “Create New API.” In this step, you will name the API, select the protocol and REST API type, and click the “Create API” button.

Next, you will need to create an HTTP POST endpoint. This endpoint will be used to execute your Lambda function, which will handle the API request.

This endpoint should be defined by the HTTP method “POST,” the domain name, and the API endpoint.

Testing the API manually

After creating your API, you can test it manually by using a Lambda function. A Lambda function is a piece of code that can execute HTTP requests.

Here are some steps to follow:

1. From the AWS Management Console, navigate to the AWS Lambda service.

2. Create a new Lambda function by clicking “Create Function.”


Choose a blueprint or create a new function from scratch. 4.

Name the function, select Node.js as the runtime, and click on “Create Function.”

5. Copy the following code into the “Function Code” section:

exports.handler = async (event) => {

return {

statusCode: 200,

body: JSON.stringify(‘true’),




After saving the code, use an HTTP request to invoke the function and test the API. If the API is set up correctly, you will receive a “true” response from the Lambda function.

Enabling CORS

If you want the API to be accessible from a browser, you will need to enable Cross-Origin Resource Sharing (CORS). CORS allows scripts running on different domains to interact and exchange data.

Here are some steps to follow:

1. From the API Gateway Console, navigate to the desired API.

2. Click on “Actions” and then select “Enable CORS.”


Select the domain name and click on Enable CORS and Replace Existing Headers.

Deploying the API

Once you have finished setting up the API Gateway, you can deploy your API. Here are some steps to follow:

Deploying the API

To deploy the API, you will need to associate it with your Lambda function. Here’s how to do it:


From the API Gateway console, navigate to the desired API. 2.

Click on “Actions” and select “Deploy API.”

3. Select the deployment stage, such as “Prod” or “Test.”


Choose the deployment options, including the Lambda function, the region (us-east-1), and the deployment description. 5.

Click on “Deploy.”

Testing the API via cURL

After deploying the API, you can verify that everything is working as expected by running a quick test using cURL. Here’s how to do it:


Copy the API URL from the “Stages” tab in the API Gateway Console. 2.

Open the terminal and type the following command:

curl -X POST -H “Content-Type: application/json” -d ‘{}’ API_URL

3. Replace “API_URL” with the URL copied in step 1, and hit enter.

You should receive a “true” response from the API if everything is set up correctly.


In conclusion, setting up and deploying an API Gateway can seem challenging at first, but it is a manageable process when you follow the steps in this article. We hope that this article has provided you with some helpful insights on how to create and deploy your own API Gateway.

Happy programming!

Additional Functionality

Creating an API Gateway is just the beginning. There are a few additional functionalities that you might want to add to your API Gateway.

One of those is removing ads, while another is analyzing API performance. We’ll cover both of these topics in more detail below.

Removing Ads

Ads are ubiquitous in our modern internet experience. They are often intrusive and can interfere with the usability of a website or application.

If you’re building an API, you might not want to include ads. Fortunately, there are several ways to remove ads from your API Gateway.

The first option is to use a paid version of the Amazon API Gateway. The paid version offers features like custom domain names, VPC links, and analytics, but more importantly, it removes ads from your API.

If you opt for this solution, you’ll need to upgrade your account to the paid version. Another option is to use an ad-blocking extension in your browser.

Ad blockers can block ads that are served on a specific domain, so if you block ads on the domain that your API Gateway is hosted on, the ads will be removed. Finally, if your API Gateway serves ads from a third-party domain, you can replace the ad code with dummy text.

This will effectively remove the ads without needing to update the code for your API Gateway.

Analyzing API Performance

Analyzing API performance is an important part of maintaining a successful API. Your API should consistently meet the performance metrics that you’ve established.

If you notice a degradation in performance, you’ll want to investigate and take corrective action. Here’s how you can analyze the performance of your API Gateway.

First, you’ll need to enable CloudWatch logs. CloudWatch logs are a mechanism that lets you monitor and store all log files generated by your API requests.

They provide detailed insights into how your API is performing, how it’s being used, and any errors that might occur. Once you have CloudWatch logs enabled, you can start analyzing your API’s performance.

Start by reviewing the logs and looking for patterns or trends. For example, see if there are any times of the day when API performance dips or if certain endpoints are more problematic than others.

You can also use API Gateway’s built-in API Monitoring feature to review your API’s performance metrics. API Monitoring provides detailed metrics on API latency, error rates, and data transfer rates, among other things.

Use these metrics to set and track performance targets and to identify any areas for improvement. Finally, you might want to consider load testing your API Gateway.

Load testing involves simulating a high volume of requests to your API to see how it performs under stress. Load testing can help you identify bottlenecks in your API architecture and ensure that your API can handle the traffic it’s intended to serve.


Whether you’re building an API for a startup or a large enterprise, adding functionality like ad removal and performance analysis can help ensure that your API Gateway is performing at its best. By understanding how to implement these additional features, you’ll be able to provide a better user experience and ensure that your API is functioning efficiently.

Remember, the key to a successful API is to continuously test, monitor, and optimize its performance. In conclusion, creating and deploying an API Gateway is a crucial aspect of building a modern internet application.

In addition, removing ads and analyzing API performance are important features that can enhance the user experience and ensure your API operates efficiently. By following the steps outlined in this article, you can create and deploy an API Gateway that meets your performance needs.

Regular analysis, maintenance, and improvement are essential for your API’s continued efficiency. The key takeaway is to optimize your API regularly to ensure optimal performance.
